Congress has passed legislation which will delay the forced shutdown of analog TV until June 12th. It has not yet been signed by President Obama but the President has called for the legislation so I think you can assume he'll sign it.
The legislation permits stations to leave their analog transmitters on past February 17th. It does not require them to do so. Nearly 700 stations have already filed notice of intent to shut off their analog transmitters on February 17th regardless of this legislation.
